PFP Ultra High NA fibers are excellent bridge fibers between high NA waveguides and low NA transmission fiber. Ultra High NA fibers provide excellent coupling efficiencies to high NA waveguides. In addition, the composition of Ultra High NA fibers are tailored to thermally expand the core during splicing, thus achieving lower splice loss to transmission fiber.
